Polymer silica gel protective film

Abstract

The invention discloses a polymer silica gel protective film, and particularly relates to the field of protective films, the polymer silica gel protective film comprises a roll core, and a PET protective film is arranged outside the roll core; the PET protective film is composed of a protective film body, a release film and oiled paper, the release film is arranged at the bottom of the protective film body, and the oiled paper is arranged outside the protective film body; the protective film body consists of a UV (ultraviolet) adhesive layer, a polymer layer, a PU (polyurethane) adhesive layer, a PET (polyethylene terephthalate) base material and an organic silicon pressure-sensitive adhesive layer, and the PU adhesive layer is arranged at the top of the PET base material. The surface of the PU adhesive is subjected to special macromolecule treatment, the effective period of macromolecules can reach 12 months or above, the antistatic effect of the PU protective film is greatly improved, the obtained macromolecule protective film is long in antistatic lasting time and stable in effect, the quality guarantee period can reach one year or above, the resistance value can reach 106-11 omega, and the service life of the macromolecule protective film is prolonged. And the antistatic effect cannot be transferred to the surface of an object to be protected to cause pollution.

Description

technical field [0001] The present invention relates to the technical field of protective film, more specifically, the present invention relates to a polymer silica gel protective film. Background technique [0002] PU protective film has largely replaced glass fiber raw insulation materials, wood, traditional rubber products, etc. Ordinary PU protective film has not been treated with polymers. Due to the accumulation of static electricity, it will cause harm during use, such as adsorption of dust, electrostatic discharge causing fire and breakdown of microelectronic components. The consequences are disastrous. Therefore, some antistatic film products have also appeared on the market, but generally speaking, there are defects such as short duration of antistatic effect, unstable antistatic effect, and poor appearance. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the embodiment of the present invention provides a pol...

AI Technical Summary

Problems solved by technology

Ordinary PU protective film has not been treated with polymers. Due to the accumulation of static electricity, it will cause harm during use, such as adsorption of dust, electrostatic discharge causing fire and breakdown of microelectronic components. The consequences are unimaginable.

Therefore, some antistatic film products have also appeared on the market, but generally speaking, there are defects such as short duration of antistatic effect, unstable antistatic effect, and poor appearance.
